A similar study by Stanford University found that participants carrying several followers of Garmin, Fitbit, Apple, and others found that 81% of patients who tested positive for coronavirus had changes in resting heart rate up to nine. days and a half before the onset of symptoms.
One of the hardest things about COVID-19 is that many people are asymptomatic, meaning they have no symptoms, but they are still contagious. This makes it difficult to contain this infection through the traditional method of identifying someone sick and quarantining them.
The ramifications of the studies are clear. “Developing a way to identify people who may be sick even before they know they are infected would really be a breakthrough in the management of COVID-19,” Dr. Hirten said. “This technology allows us to not only track and predict health outcomes, but also intervene in a timely and remote manner, which is essential during a pandemic that requires people to stay separate.”
Researchers are not the only ones who have noticed the first symptoms of COVID-19 that a smart watch can detect. A company called NeuTigers, born from research at Princeton University, has developed an artificial intelligence product called CovidDeep that can help identify people with the virus in clinical situations or nursing homes.
The company used a portable clinical monitoring device for patients, the Empatica E4, to do various skin readings, heart rate and blood pressure. By entering this information into CovidDeep, they discovered that they could detect the virus at a rate of 90%, more accurately than the usual temperature tests. Finally, they plan to produce their own app that can work with Fitbit, Withings, Apple, Samsung and other smartwatches.
Even without custom algorithms, a smartwatch or portable device could still be useful. Recently, the PGA Tour started using Whoop health trackers and this may have helped player Nick Watney realize it was positive. “They’ve done studies where, if the respiratory rate increases overnight … that’s kind of a telltale sign that it might have something,” senior champion Rory McIlroy said in June. “It was actually his Whoop who said that [Watney] the respiratory rate increased and so he thought that maybe he could have it ”.
